What are the heat resistance grades of insulating materials? Share with you today:
(1) Y level Insulation materials: Natural textiles such as wood, cotton, fibers, textiles based on acetate and polyamide, and plastics that decompose easily and have a low melting point. Limit working temperature: 90 degrees.
(2) Grade A Insulation materials: Class Y materials working in mineral oil and impregnated with oil or oleoresin compound glue, insulation of enameled wire, varnished cloth, lacquered wire and oily varnish. asphalt paint etc. Limit working temperature: 105 degrees.
(3) Class E Insulation material: composite of polyester film and A-grade material, glass cloth, oily resin paint, polyvinyl acetal high-strength enameled wire, vinyl acetate heat-resistant enameled wire. Limit working temperature: 120 degrees.
(4) Grade B Insulating materials: polyester film, mica impregnated with suitable resin bonding, glass fiber, asbestos, etc., polyester varnish, polyester enameled wire. Limit working temperature: 130 degrees.
(5) Grade F Insulation materials: mica products reinforced with organic fiber materials, glass wool and asbestos, glass wool cloth, laminated products based on glass wool cloth and asbestos fibers, mica powder products reinforced with inorganic materials and stone belts are chemically and thermally stable Polyester or alkyd materials with better resistance, composite silicone organic polyester paint. Limit working temperature: 155 degrees.
